BACKGROUND

1. Field of the Invention

The present invention generally relates to a reinforced vehiclestructure. More particularly, the present invention relates to areinforced vehicle structure for securing a vehicle accessory, such as ashelving arrangement, in a cargo area of a vehicle.

2. Background Information

Reinforcement components are often used in vehicles to increase thedurability or rigidity of the vehicle body structure. For example, areinforcement component may include an additional layer of material or athickened component in an area where forces appear to be particularlyconcentrated, or in an area of particular importance where enhancedstress resistance is desired. Vehicle bodies are also sometimesmanufactured to include prefabricated attachment points. Such attachmentpoints may be utilized, for example, as tie-down locations in order tomore reliably and efficiently secure cargo.

Prefabricated attachment points may also be included in a vehicle designto give customers the ability to add permanent custom equipment orcomponents, which may be sold as dealer-installed accessories or addedby aftermarket up-fitters. For example, such an attachment point maycomprise a nut weld, which can be an accessible threaded apertureincluding a nut that is welded to the opposite-facing side of a bodypanel. However, the addition of equipment and components to vehiclesafter the vehicles leave the factory can impose increased stresses andfatigue on the vehicle body structures, which may not have beenaccounted for in the initial design of the vehicles. This is especiallyrelevant at attachment points in the vehicle body structure, whereforces imposed by equipment and components are often concentrated.

DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to thedrawings. It will be apparent to those skilled in the art from thisdisclosure that the following descriptions of the embodiments areprovided for illustration only and not for the purpose of limiting theinvention as defined by the appended claims and their equivalents.

Referring initially to FIGS. 1-8, a vehicle 10 includes a reinforcedvehicle structure 12. The reinforced vehicle structure 12 in thisexample is configured in the cargo compartment 14 at the rear interiordriver side of the vehicle 10 and at the rear interior passenger side ofthe vehicle 10. However, the reinforced vehicle structure 12 can bepresent at either the rear interior driver side or the rear interiorpassenger side, or at any other suitable location within the interior ofthe vehicle 10.

As shown in FIGS. 2, 3 and 5-8, a portion of the reinforced vehiclestructure 12 located at the rear interior driver side of the vehicle 10includes a vehicle floor 16 having an underbody floor surface 18 facingan underbody of the vehicle 10 and an interior floor surface 20 facingan interior of the vehicle 10. The vehicle floor 16 is made of a metaltypically used in automotive manufacture or any other suitable material.A reinforcement member 22 is mounted to the underbody floor surface 18by welding, riveting, screws, or any other suitable fasteners. Thereinforcement member 22 is also made of a metal that can be the same asthe metal of vehicle floor 16, or any other suitable metal or material.

In this example, the reinforcement member 22 is mounted proximate to awheel well opening 24 in the vehicle floor 16. As shown, for example, inFIGS. 5-9, the vehicle floor 16 has a first shaped edge 26 having afirst shape defining the wheel well opening 24. Similarly, thereinforcement member 22 has a second shaped edge 28 having a secondshape, with a portion of the second shape substantially corresponding tothe first shape. Moreover, a portion of the underbody floor surface 18of the vehicle floor 16 has a first shape and the reinforcement member22 has a second shape substantially corresponding to the first shape toenable the reinforcement member 22 to mate with the portion of theunderbody floor surface 18 when the reinforcement member 22 is mountedto the underbody floor surface 18.

That is, as shown in FIG. 8, in particular, the vehicle floor 16includes a lateral floor portion 30 that includes the interior andunderbody floor surfaces 20 and 18, and a floor flange 32 extendingdownward from the lateral floor portion 30. The reinforcement memberincludes a lateral reinforcement portion 34 and a reinforcement flange36 extending downward from the lateral reinforcement portion 34.Accordingly, the lateral reinforcement portion 34 and reinforcementflange 36 are positioned proximate to the lateral floor portion 30 andfloor flange 32, respectively, when the reinforcement member 22 ismounted to the underbody floor surface 18 of the vehicle floor 16.However, the reinforcement member 22 can be mounted at any othersuitable location along the vehicle floor 16.

An accessory attachment member 38 is mounted to the interior floorsurface 20. That is, as discussed above, the vehicle 10 includes a cargocompartment 14. The accessory attachment member 38 is mounted inside thecargo compartment 14 to the interior floor surface 20 of the vehiclefloor 16. The accessory attachment member 38 is made of a metal, such asthat of vehicle floor 16 or reinforcement member 22, or any othersuitable metal or material. In this example, the accessory attachmentmember 38 has a width W1 extending in a lateral direction of the vehicle10, and the reinforcement member 22 has a width W2 extending in thelateral direction that is greater than the first width W1 as shown, forexample, in FIG. 5. Furthermore, the reinforcement member 22 has alength L1 extending in a lengthwise direction of the vehicle 10, and theaccessory attachment member 38 has a length L2 extending in thelengthwise direction that is greater than the length L1. In thisexample, the vehicle floor 16 further includes at least one supportmember 40 having a length extending in a lateral direction of thevehicle 10, and at least one support member 41 having a length extendingin a lengthwise direction of the vehicle 10. In this example, theaccessory attachment member 38 extends along the interior floor surface20 over the support member 40 and is at least partially supported by thesupport member 40 or members 40. Also, the accessory attachment member38 has a C-shaped cross-section in this example forming a recess channel43, but can have any desired cross-section.

In this example, a plurality of mounting structures 42 are spaced alongthe reinforcement member 22 and extend through the vehicle floor 16 tocouple the accessory attachment member 38 to the reinforcement member22. At least one of the mounting structures 42 includes a welded member44 that is attached by a weld to a surface 46 of the reinforcementmember 22 facing away from the vehicle floor 16, and aligned with afastening aperture 48 formed in the reinforcement member 22 throughwhich a portion 50 of the at least one of the mounting structures 40passes. In this example, the portion 50 can include a screw thatthreadedly engages with the welded member 44. Alternatively, the portion50 can include rivets or any other suitable fasteners. Furthermore, aspacer 51 can be present between the bottom surface 53 of the accessoryattachment member 38 and interior floor surface 20 as indicated toposition the accessory attachment member 38 at the appropriate heightabove the interior floor surface 20. The portion 50 of the mountingstructure 42 passes through an opening 54 in the spacer 51. The spacer51 can be arranged as individual spacers present at each of the mountingstructure locations, or a continuous spacer that extends along all or aportion of the accessory attachment member 38 and has openings throughwhich the respective portions 50 of the mounting structure 42 can pass.

Since the accessory attachment member 38 has a C-shaped cross section inthis example, the accessory attachment member 38 has a horizontallyextending portion 52 that extends in a horizontal direction of thevehicle 10, and at least one vertical portion 55 that extends transverseto the horizontally extending portion 52. The plurality of mountingstructures 42 couple the horizontally extending portion 52 of theaccessory attachment member 38 to the reinforcement member 22. Thevertical portions 55 extend in a vertical direction of the vehicle 10when the accessory attachment member 22 is mounted to the interior floorsurface 20. The accessory attachment member 38 further has secondhorizontally extending portions 56 that extend in a horizontal directionof the vehicle 10 from the vertical portions 55, and the verticalportions 55 space the second horizontally extending portions 56 apartfrom the horizontally extending portion 52 as shown.

As further illustrated in FIGS. 3 and 10, for example, the accessoryattachment member 38 is further configured to couple to a shelvingmember 60 to secure the shelving member 60 inside the vehicle 10. Theshelving member 60 can be made of metal or any other suitable material.As shown in FIG. 10, a connecting member 62 includes a coupling member64 that rests on the horizontally extending portion 52 of the accessoryattachment member 38, is slidably received in the recess channel 43formed by the C-shaped cross section of the accessory attachment member38, and is retained by the second horizontally extending portions 56. Anextension portion 66 of the coupling member 64 passes through an opening68 in the shelving member 60. A washer 70, and nut 72 that is threadedlysecured to the extension portion 66, secures the shelving member 60 tothe accessory attachment member 38 in this example. However, anysuitable type of connector, such as a screw, snap fit connection, and soon can be used to secure the shelving member 60 to the accessoryattachment member 38.

As shown in FIGS. 2, 3, 5, 8, 11, 12, 14, 15, 17 and 19, the portion ofthe reinforced vehicle structure 12 at the rear driver side of thevehicle 10 includes a vehicle wall 80 having an outer wall surface 82facing an outboard direction of the vehicle 10 and an inner wall surface84 facing an inboard direction of the vehicle 10. The vehicle wall 80 ismade of a metal typically used in automotive manufacture or any othersuitable material. A reinforcement member 86 is mounted to the outerwall surface 82 by welding, riveting, screws, or any other suitablefasteners. The reinforcement member 86 is also made of a metal that canbe the same as the metal of vehicle wall 80, or any other suitable metalor material.

A portion of the outer wall surface 82 of the vehicle wall 80 has afirst shape and the reinforcement member 86 has a second shapesubstantially corresponding to the first shape to enable thereinforcement member 86 to mate with the portion of the outer wallsurface 82 when the reinforcement member 86 is mounted to the outer wallsurface 82. In this example, the vehicle wall 80 includes a wall uprightportion 88 that includes the inner and outer wall surfaces 84 and 82,respectively, and a wall lateral portion 90 extending outboard from theupright portion 88. Furthermore, the reinforcement member 86 includes areinforcement upright portion 92 and a reinforcement lateral portion 94extending outboard from the reinforcement upright portion 92. Thereinforcement upright portion 92 and reinforcement lateral portion 94are positioned proximate to the wall upright portion 88 and wall lateralportion 90, respectively, when the reinforcement member 86 is mounted tothe outer wall surface 82 of the vehicle wall 80. Also, thereinforcement member 86 can be mounted proximate to a roof rail 96 ofthe vehicle 10 when the reinforcement member 86 is mounted to the outerwall surface 82.

An accessory attachment member 100 is mounted inside the cargocompartment 14 to the inner wall surface 84 at an upper portion of thevehicle wall 80 in this example. The accessory attachment member 100 ismade of a metal, such as that of vehicle wall 80 or reinforcement member86, or any other suitable metal or material. In this example, theaccessory attachment member 100 has a height H1 extending in a verticaldirection of the vehicle 10, and the reinforcement member 86 has aheight H2 extending in the vertical direction that is greater than theheight H1.

Furthermore, the accessory attachment member 100 in this example has aC-shaped cross-section forming a recess channel 101 therein. That is,the accessory attachment member 100 has a vertically extending portion102 that extends in a generally vertical direction of the vehicle 10,and at least one horizontal portion 104 that extends transverse to thevertically extending portion 102. Specifically, the horizontal portions104 extend in a generally inboard direction of the vehicle 10 when theaccessory attachment member 100 is mounted to the inner wall surface 84.The accessory attachment member 100 further has second verticallyextending portions 106 that extend in a generally vertical direction ofthe vehicle 10 from the horizontal portions 104. Accordingly, thehorizontal portions 104 space the second vertically extending portions106 apart from the vertically extending portion 102.

A plurality of mounting structures 110 are spaced along thereinforcement member 86 and extend through the vehicle wall 80 to couplethe accessory attachment member 100 to the reinforcement member 86. Atleast one of the mounting structures 110 includes a welded member 112that is attached by a weld to a surface 114 of the reinforcement member86 facing away from the vehicle wall 80. The welded member 112 isaligned with a fastening aperture 116 formed in the reinforcement member86 through which a portion 118 of the mounting structure 110 passes. Inthis example, the portion 118 of the mounting structure 110 can includea bolt that is threadedly secured to the welded member 112 to secure theaccessory attachment member 100 to the reinforcement member 86. However,the portion 118 of the mounting structure 110 can include a rivet, screwor any other suitable type of fastener. In this example, the pluralityof mounting structures 110 couple the vertically extending portion 102of the accessory attachment member 100 to the reinforcement member 86.

Furthermore, a spacer 117 can be present between the accessoryattachment member 100 and inner wall surface 84 as indicated to offsetthe accessory attachment member 100 a desired distance from the innerwall surface 84. The portion 118 of the mounting structure 110 passesthrough an opening 119 in the spacer 117. The spacer 117 can be arrangedas individual spacers present at each of the mounting structurelocations, or a continuous spacer that extends along all or a portion ofthe accessory attachment member 100 and has openings through which therespective portions 118 of the mounting structure 110 can pass.

As further illustrated, a trim member 120, such as an interior trimpanel of a type that is typically present in vehicles, is disposedproximate to the inner wall surface 84. In this example, the accessoryattachment member 100 is mounted to the inner wall surface 84 such thatthe trim member 120 that is disposed proximate to the inner wall surface84 is positioned between the accessory attachment member 100 and thevehicle wall 80. Furthermore, the reinforcement member 86 includes atleast one fastening aperture 122 that receives a portion of a mountingmember 124 of the trim member 120 can be secured proximate to thevehicle wall 80 in any suitable manner.

As further illustrated in FIGS. 3 and 10, for example, the accessoryattachment member 100 is further configured to couple to the shelvingmember 60 to further secure the shelving member 60 inside the vehicle10. A connecting member (not shown) similar to connecting member 62 asdiscussed above can be slidably received in the recess channel 101formed by the C-shaped cross section of the accessory attachment member100, and is coupled to the shelving member 60 in a manner similar toconnecting member 62 to secure the shelving member 60 to the accessoryattachment member 100 in this example. However, any suitable type ofconnector, such as a screw, snap fit connection, and so on can be usedto secure the shelving member 60 to the accessory attachment member 100.

As further shown, for example, in FIGS. 2, 3, 11, 12 and 17-19, thereinforced vehicle structure 12 can further include a second vehiclewall 130 extending transverse to the vehicle wall 80, which can bereferred to as a first vehicle wall 80. The second vehicle wall 130includes a second outer wall surface 132 facing an exterior of thevehicle 10 and a second inner wall surface 134 facing an interior of thevehicle 10. The reinforced vehicle structure 12 also includes areinforcement member 136 having a first end 138 mounted to the accessoryattachment member 100 and a second end 140 mounted to the second innerwall surface 134. The mounted reinforcement member 136 therefore extendsin a direction that is not parallel to either of the first and secondvehicle walls 80 and 130.

Furthermore, in this example, a mounting member 142 is mounted to thesecond inner wall surface 134. For instance, the mounting member 142includes a plurality of openings 144 that align with openings 146 in thesecond vehicle wall 130. A reinforcement member 148, such as a weldedmember, can be attached to the second outer surface 132 by welding or inany other suitable manner. The reinforcement member 148 can include anopening 150 therein that is aligned with an opening 146 in the secondvehicle wall 130. Accordingly, a mounting structure 152, such as a bolt,can pass through respective openings 144 and 146 and threadedly engagewith the opening 150 in the reinforcement member 148 to secure themounting member 142 to the second vehicle wall 130. In this example, aplurality of mounting structures 152 are spaced along the mountingmember 142 and extend through the corresponding openings 144 in themounting member 142, through the corresponding openings 146 in secondvehicle wall 130, and into the corresponding openings 150 in thereinforcement members 148, to couple the mounting member 142 to thesecond vehicle wall 130.

The mounting member 142 in this example further includes a raisedportion 154 that extends away from the second inner wall surface 134.The plurality of mounting structures 152 are spaced along portions ofthe mounting member 142 other than the raised portion 154, and extendthrough the second vehicle wall 130 to couple the mounting member 142 tothe second vehicle wall 130.

A vehicle accessory 156 having a first accessory surface 158 and asecond accessory surface 160 on a side opposite to the first accessorysurface 158 is positioned between the mounting member 142 and thereinforcement member 136. The vehicle accessory 156 can be, for example,a side panel of shelving member 60, or a different vehicle accessorycomponent. In this example, the first accessory surface 158 contacts themounting member 142 and, in particular, the raised portion 154 of themounting member 142. The second accessory surface 160 contacts thereinforcement member 136.

As further shown in this example, the second end 140 of thereinforcement member 136 is connected to the mounting member 142 by acoupling structure 162 which, in this example, includes a bolt 164 andnut 166. However, the coupling structure 162 can include any suitabletype of coupling arrangement. The coupling structure 162 is positionedbetween a plurality of the mounting structures 152 and extends throughan opening 168 in the second end 140 of the reinforcement member 136, anopening 170 in the vehicle accessory 156, and an opening 172 in theraised portion 154 of the mounting member 142, to couple the second end140 of the reinforcement member 136 to the mounting member 142.Accordingly, the second end 140 of the reinforcement member 136 isconnected to the raised portion 154 of the mounting member 142. Thus,the mounting member 142 mounts the second end 140 of the reinforcementmember 136 to the second inner wall surface 134.

With regard to the first end 138 of the reinforcement member 136, asillustrated, a coupling member 180 couples the first end 138 of thereinforcement member 136 to the accessory attachment member 100. Asdiscussed above, the accessory attachment member 100 has a C-shapedcross-section defining a recess 101, and the coupling member 180 has afirst coupling end 182 that passes through an opening 184 in the firstend 138 of the reinforcement member 136 and a second coupling end 186that couples to the accessory attachment member 100. That is, the firstcoupling end 182 can threadedly engage with a nut 188 to secure thecoupling member 180 to the first end 138 of the reinforcement member136. The second coupling end 186 is received in the recess 101 of theaccessory attachment member 100 to couple the first end 138 of thereinforcement member 136 to the accessory attachment member 100.

As further shown in FIGS. 2, 4, 5 and 20-22, a portion of the reinforcedvehicle structure 12 located at the rear interior passenger side of thevehicle 10 includes features similar to those discussed above withregard to the rear interior driver side of the vehicle 10. For example,the portion of the reinforced vehicle structure 12 located at the rearinterior passenger side of the vehicle 10 includes the vehicle floor 16having the underbody floor surface 18 facing an underbody of the vehicle10 and the interior floor surface 20 facing an interior of the vehicle10. A reinforcement member 200 is mounted to the underbody floor surface18 by welding, riveting, screws, or any other suitable fasteners. Thereinforcement member 200 is also made of a metal that can be the same asthe metal of vehicle floor 16, or any other suitable metal or material.

In this example, the reinforcement member 200 is mounted proximate to awheel well opening 202 in the vehicle floor 16. As shown, for example,in FIGS. 5 and 20-22, the vehicle floor 16 has a first shaped edge 204having a first shape defining the wheel well opening 202. Similarly, thereinforcement member 200 has a second shaped edge 206 having a secondshape, with a portion of the second shape substantially corresponding tothe first shape. Moreover, a portion of the underbody floor surface 18of the vehicle floor 16 has a first shape and the reinforcement member22 has a second shape substantially corresponding to the first shape toenable the reinforcement member 200 to mate with the portion of theunderbody floor surface 18 when the reinforcement member 200 is mountedto the underbody floor surface 18.

That is, as shown in FIG. 22, in particular, the vehicle floor 16includes a lateral floor portion 208 that includes the interior andunderbody floor surfaces 20 and 18, and a floor flange 210 extendingdownward from the lateral floor portion 30. The reinforcement memberincludes a lateral reinforcement portion 212 and a reinforcement flange214 extending downward from the lateral reinforcement portion 212.Accordingly, the lateral reinforcement portion 212 and reinforcementflange 214 are positioned proximate to the lateral floor portion 208 andfloor flange 210, respectively, when the reinforcement member 200 ismounted to the underbody floor surface 18 of the vehicle floor 16.However, the reinforcement member 200 can be mounted at any othersuitable location along the vehicle floor 16.

An accessory attachment member 220 is mounted to the interior floorsurface 20 inside the cargo compartment 14 of the vehicle 10. Theaccessory attachment member 220 is made of a metal, such as that ofvehicle floor 16 or reinforcement member 200, or any other suitablemetal or material. In this example, the accessory attachment member 220has a width W3 extending in a lateral direction of the vehicle 10, andthe reinforcement member 200 has a width W4 extending in the lateraldirection that is greater than the width W3 as shown, for example, inFIG. 5. Furthermore, the reinforcement member 200 has a length L3extending in a lengthwise direction of the vehicle 10, and the accessoryattachment member 220 has a length L4 extending in the lengthwisedirection that is greater than the length L3.

As discussed above, the vehicle floor 16 further includes at least onesupport member 40 having a length extending in a lateral direction ofthe vehicle 12. However, in this example, the accessory attachmentmember 220 at the rear passenger side of the vehicle 10 does not extendover the support member 40 and is thus not structurally supported by thesupport members 40 or 41. Accordingly, the length L3 of thereinforcement member 200 is longer than the length L5 of the wheel wellopening 202 extending in a longitudinal direction of the vehicle 10, asshown in FIGS. 5, 20 and 21. Also, the accessory attachment member 220has a C-shaped cross-section forming a recess channel 221 in thisexample, but can have any desired cross-section.

In this example, a plurality of mounting structures 222 are spaced alongthe reinforcement member 200 and extend through the vehicle floor 16 tocouple the accessory attachment member 220 to the reinforcement member200. At least one of the mounting structures 222 includes a weldedmember 224 that is attached by a weld to a surface 226 of thereinforcement member 200 facing away from the vehicle floor 16, andaligned with a fastening aperture 228 formed in the reinforcement member200 through which a portion 230 of the at least one of the mountingstructures 222 passes. In this example, the portion 230 can include ascrew that threadedly engages with the welded member 224. Alternatively,the portion 230 can include rivets or any other suitable fasteners.Furthermore, a spacer 231 can be present between the bottom surface 233of the accessory attachment member 220 and interior floor surface 20 asindicated to position the accessory attachment member 220 at theappropriate height above the interior floor surface 20. The portion 230of the mounting structure 222 passes through an opening 234 in thespacer 231. The spacer 231 can be arranged as individual spacers presentat each of the mounting structure locations, or a continuous spacer thatextends along all or a portion of the accessory attachment member 220and has openings through which the respective portions 230 of themounting structure 222 can pass.

Since the accessory attachment member 220 has a C-shaped cross sectionin this example, the accessory attachment member 220 has a horizontallyextending portion 232 that extends in a horizontal direction of thevehicle 10, and at least one vertical portion 235 that extendstransverse to the horizontally extending portion 232. The plurality ofmounting structures 222 couple the horizontally extending portion 232 ofthe accessory attachment member 220 to the reinforcement member 200. Thevertical portions 235 extend in a vertical direction of the vehicle 10when the accessory attachment member 220 is mounted to the interiorfloor surface 20.
